Question

I have a string coming from a UI that contains control characters such as line feeds and carrage returns.

I would like to do something like this:

String input = uiString.replaceAll(<regex for all control characters> , "")

Surely this has been done before!?

Answer 1

Something like this should do the trick:

String newString = oldString.replaceAll("[\u0000-\u001f]", "");
